Vasculature of the heart

Question 1

Where does the aorta come form?

Answer 1

Left ventricle of the heart

Question 2

Where does the superior vena cava come from?

Answer 2

From the left and right brachiocephalic veins merging

Question 3

Where does the pulmonary artery come from?

Answer 3

Right ventricle

Question 4

What does the superior vena cava do?

Answer 4

Carry oxygen-poor blood to the right atrium, where it moves into the right ventricle and then to the lungs to trade in carbon dioxide for oxygen.

Question 5

What does the aorta do?

Answer 5

The aorta is the main artery that carries blood away from your heart to the rest of your body.

Question 6

What does the pulmonary artery do?

Answer 6

The pulmonary arteries carry blood from the right side of the heart to the lungs.

Question 7

What do pulmonary veins do?

Answer 7

Transfer freshly oxygenated blood from the lungs to the left atria of the heart

Question 8

List the arteries and veins on the posterior surface of the heart going from left to right

Answer 8

Right coronary artery 
Right marginal artery 
Left anterior descending artery 
Left coronary artery 
Left marginal artery 

Coronary sinus which gives off:

Great cardiac vein 
Left marginal vein 
Left posterior ventricular vein 
Middle cardiac vein 
Small cardiac vein

Question 9

What does the left circumflex artery do?

Answer 9

Supplies left atrium and left ventricle

Question 10

Where does the left circumflex artery originate from?

Answer 10

Arises from the bifurcation of the left main coronary artery

Question 11

Where does the left anterior descending artery originate from?

Answer 11

Arises from the bifurcation of the left main coronary artery

Question 12

What two major coronary arteries that arise from the bifurcation of the left main coronary artery?

Answer 12

Circumflex artery

Left anterior descending artery

Question 13

What does the left anterior descending artery do?

Answer 13

Supplies the right ventricle, left ventricle, and interventricular septum

Question 14

What does the left marginal artery do?

Answer 14

Supplies the left ventricle

Question 15

Where does the left marginal artery originate?

Answer 15

The left marginal artery of the heart is a branch of the circumflex artery

Question 16

What does the right marginal artery do?

Answer 16

Supplies the right ventricle and apex

Question 17

Where does the right marginal artery come from?

Answer 17

The right coronary artery

Question 18

What does the right coronary artery do?

Answer 18

Supplies the right atrium and the right ventricle

Question 19

Where does the right coronary artery come from?

Answer 19

Root of the aorta

Question 20

What are the two main arteries that come from the root of the aorta?

Answer 20

The two primary coronary arteries, the right coronary artery (RCA) and the left main coronary artery (LMCA).

Question 21

What does the posterior interventricular artery do?

Answer 21

Supplies the left and right ventricles and the interventricular septum.

Question 22

Where does the posterior interventricular artery come from?

Answer 22

The right coronary artery

Question 23

What does venous drainage of the heart mostly take place in?

Answer 23

Through the coronary sinus

Question 24

What are the tributaries?

Answer 24

A smaller branch draining waste-products in blood into a larger vein.

Question 25

What are the main tributaries of the coronary sinus?

Answer 25

Great cardiac vein
Small cardiac vein
Middle cardiac vein
Posterior cardiac vein

Question 26

Where does the great cardiac vein originate from?

Answer 26

It originates at the apex of the heart and ascends in the anterior interventricular groove.

Question 27

Where is the small cardiac vein located?

Answer 27

Located on the anterior surface of the heart, in a groove between the right atrium and right ventricle.

It travels within this groove onto the posterior surface of the heart, where it empties into the coronary sinus.

Question 28

Where does the middle cardiac vein begin and ascend to?

Answer 28

Begins at the apex of the heart and ascends in the posterior interventricular groove to empty into the coronary sinus.

Question 29

Where is the posterior cardiac vein located?

Answer 29

Located on the posterior surface of the left ventricle.

It lies to the left of the middle cardiac vein and empties into the coronary sinus.
